SUSE SLES12 Security Update : kernel (SUSE-SU-2016:2658-1) (Dirty COW)

This script is Copyright (C) 2016-2017 Tenable Network Security, Inc.

Synopsis :

The remote SUSE host is missing one or more security updates.

Description :

This update for the Linux Kernel 3.12.60-52_49 fixes several issues.
The following security bugs were fixed :

- CVE-2016-5195: A local privilege escalation using
MAP_PRIVATE was fixed, which is reportedly exploited in
the wild (bsc#1004419).

- CVE-2016-4997: The compat IPT_SO_SET_REPLACE and
IP6T_SO_SET_REPLACE setsockopt implementations in the
netfilter subsystem in the Linux kernel allowed local
users to gain privileges or cause a denial of service
(memory corruption) by leveraging in-container root
access to provide a crafted offset value that triggers
an unintended decrement (bsc#986377).

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.
